THE MAINTENANCE DIALOG FOR ZTABLE IS INCOMPLETE OR NOT DEFINED --ERROR

Goto transaction code SE54 then enter the table name for which you have created the Table Maintenance Generator.
Then choose Generated objects
And click on display.
It will show the table maintenance dialog you have generated for the table, if doesn't show then create the table maintenance generator again,

This Error usually occurs when you are creating Table Maintenance Generator, after clicking on Find screen numbers..people usually forget to press on the CREATE button (beside the Find screen numbers)
when you don't press on CREATE  button you are doing the whole procedure correctly  but not creating it, so the system is not creating the Table Maintenance Generator for that particular table. So when you goto
SM30 and try to maintain entries you will get this error.

Hope you understand.
